Precast pile driving issues
Precast pile driving issues
(OP)
If a precast concrete pile is cast at the plant with its top head out-of-square, does anyone have a feel for how badly it can be out-of-square before it gets risky to damage the pile? I know pads are placed on top of the pile so Im assuming there is some play in the spec?

More importantly you should be considering the long term durability. If you are out of square, you need to check that your minimum covers have been achieved where they will matter.

We've never had (accepted) a pile that was out of tolerance. Most of our piles are driven to a specified blow-count and cut off in the field. The pile butts in the field have no problem meeting ACI tolerances and that's a field cut.

Forensic: What's your location?

The piles arrive on site with heads out of square (top end not perpendicular to the longitudinal axis) say up to 1/2-inch out of square, the piledriving contractor tries to drive them and the top 10 feet of the piles spall apart. Seems like a stupid decision to attempt to install them unless there is a standard method to accommodate out of square piles.
